When you have overcome one temptation, you must be ready to enter the lists with another. As distrust, in some sense, is the mother of safety, so security is the gate of danger. A man had need to fear this most of all, that he fears not at all.

Our best hope for the future is that the intellect - the scientific spirit, reason - should in time establish a dictatorship over the human mind. The very nature of reason is a guarantee that it would not fail to concede to human emotions, and to all that is determined by them, the position to which they are entitled. But the common pressure exercised by such a domination of reason would prove to be the strongest unifying force among men, and would prepare the way for further unifications. Whatever, like the ban laid upon thought by religion, opposes such a development is a danger for the future of mankind.

The opportunities of making great sacrifices for the good of mankind are of rare occurrence; and he who remains inactive till it is in his power to confer signal benefits or yield important services is in imminent danger of incurring the doom of the slothful servant.

Kindness and intelligence don’t always deliver us from the pitfalls and traps: there are always failures of love, of will, of imagination. There is no way to take the danger out of human relationships.

The inlet of a man's mind is what he learns; the outlet is what he accomplishes. If his mind is not fed by a continued supply of new ideas which he puts to work with purpose, and if there is no outlet in action, his mind becomes stagnant. Such a mind is a danger to the individual who owns it and is useless to the community.

Security is mostly a superstition. It does not exist in nature, nor do the children of men as a whole experience it. Avoiding danger is no safer in the long run than outright exposure. The fearful are caught as often as the bold. Faith alone defends.

We are not asking our children to do their own best but to be the best. Education is in danger of becoming a religion based on fear; its doctrine is to compete. The majority of our children are being led to believe that they are doomed to failure in a world which has room only for those at the top.

We have kept our children so busy with “useful” and “improving” activities that we are in danger of raising a generation of young people who are terrified of silence, of being alone with their own thoughts.

The most precious of all possessions, is power over ourselves; power to withstand trial, to bear suffering, to front danger; power over pleasure and pain; power to follow convictions, however resisted by menace and scorn; the power of calm reliance in scenes of darkness an storms. He that has not a mastery over his inclinations; he that knows not how to resist the importunity of present pleasure or pain, for the sake of what reason tells him is fit to be done, wants the true principle of virtue and industry, and is in danger of never being good for anything.

The greatest danger that faces this country is the danger of moral lassitude - liberty turned to license, rights demanded and duties shirked, the moral sense deteriorating, the traditions and standards of the nation weakened, the spiritual forces within it losing ground.
